Cool. I have heard that some cultures, particularly in Southeast Asia and the Middle East, prohibit the use of needles for various culutural and religious reasons. This new technique could also be useful to them for drugs that are normally injected by syringe.

If they object to needles, what makes you think they would be open to having something implanted in their body?That sounds surgical and would more than likely in itself involve the use of needles for anesthesia to prep for the surgery.
(one would think)
